Werner Lemberg 4e659d7e 2016-09-03T18:14:00 [truetype] More fixes for handling of GX deltas. Problems reported by Bob Taylor <Bob.Taylor@monotype.com>. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix rough sanity test for glyph variation array header size. Always set stream position before reading packed x and y deltas. Fix thinko w.r.t. `localpoints' array.
Werner Lemberg a4c2a311 2016-08-22T19:32:34 [truetype] Fix `MPS' instruction. According to Greg Hitchcock, MPS in DWrite really returns the point size. * src/truetype/ttobjs.h (TT_SizeRec): Add `point_size' member. * src/truetype/ttdriver.c (tt_size_request): Set `point_size'. * src/truetype/ttinterp.h (TT_ExecContextRec): Add `pointSize' member. * src/truetype/ttinterp.c (TT_Load_Context): Updated. (Ins_MPS): Fix instruction.
Werner Lemberg cf4224ad 2016-08-16T06:44:23 [truetype] Fix compiler warning. * src/truetype/ttgload.c (load_truetype_glyph): Add cast.
Alexei Podtelezhnikov 125f2b63 2016-08-11T23:40:05 * src/truetype/ttinterp.c (Pop_Push_Count): Revert changes.
Alexei Podtelezhnikov 49d474f6 2016-08-11T23:03:09 * src/truetype/ttinterp.c (TT_RunIns): Minor and formatting.

Werner Lemberg 053943a7 2016-07-30T00:27:48 [truetype] Comment.
Werner Lemberg fae4ec05 2016-07-29T06:43:32 [sfnt, truetype] Don't abort on invalid `maxComponentDepth'. Since 2016-05-16 we detect infinite recursion directly. * src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust `maxComponentDepth'. * src/truetype/ttgload.c (load_truetype_glyph): Don't abort if `maxComponentDepth' is not valid. Instead, simply adjust its value and emit a tracing message.
Hin-Tak Leung 3a528bbe 2016-07-22T06:59:36 [truetype] Record the end of IDEFs. To match the logic in FDEF. The value of the end is only used for bound-checking in `Ins_JMPR', so it may not have been obvious that it was not recorded. Tested (as part of Font Validator 2.0) all the fonts on Fedora and did not see any change. * src/truetype/ttinterp.c (Ins_IDEF): Updated.
Werner Lemberg 7f63105c 2016-07-19T21:35:58 [truetype] Sanitizer fix, second try. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary tests and use only one slot more.
Werner Lemberg 9f6426eb 2016-07-19T07:23:17 Thinko; fix previous commit.
Werner Lemberg e69f34b1 2016-07-19T07:06:19 [truetype] Sanitizer fix. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Increase array to fix nested loops.
Werner Lemberg a3b70d76 2016-07-18T06:23:36 [truetype] Make GETDATA work only for GX fonts. * src/truetype/ttinterp.c (opcode_name): Updated. (Ins_GETDATA): Only define for `TT_CONFIG_OPTION_GX_VAR_SUPPORT'. (TT_RunIns): Updated.
Werner Lemberg 8c93013c 2016-07-17T22:40:31 [truetype] Add support for Apple's GETDATA[], opcode 0x92 bytecode instruction. It always returns 17, and we have absolutely no idea what it is good for... * src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated. (Ins_GETDATA): New function. (TT_RunIns): Add it.
Werner Lemberg e0843609 2016-07-16T18:46:28 [truetype] Add bytecode support for GX variation fonts. This commit implements undocumented (but confirmed) stuff from Apple's old bytecode engine. GETVARIATION[], opcode 0x91 This opcode pushes normalized variation coordinates for all axes onto the stack (in 2.14 format). Coordinate of first axis gets pushed first. GETINFO[], selector bit 3 If GX variation support is enabled, bit 10 of the result is set to 1. * src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H. (opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated. (Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector bit 3, checking support for variation glyph hinting. (Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function to implement opcode 0x91. (TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.
Werner Lemberg 32a32062 2016-07-16T16:39:26 [truetype] Fix GETINFO bytecode instruction. * src/truetype/ttinterp.c (Ins_GETINFO): Fix return value for stretching information.
Behdad Esfahbod 69446ddc 2016-07-16T10:52:38 [truetype] Make all glyphs in `Zycon' GX font work. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix boundary tests.
Werner Lemberg a3b61253 2016-07-16T08:16:16 [truetype] Fix GX delta tracing. * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Trace relative point movements.
Werner Lemberg f147fb28 2016-07-16T07:06:21 [truetype] More fixes for GX. This finally fixes the rendering of the cyclist and the lizard in the `Zycon' font. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point index is always cumulative. (tt_handle_deltas): Rename to... (tt_interpolate_deltas): ... This. Add new parameter for output point array. Update caller. (TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds the intermediate results of `tt_interpolate_deltas' that are to be added to `outline->points'.
Nikolaus Waxweiler 86eb43a9 2016-07-16T06:37:57 * src/truetype/ttinterp.c (Ins_MIRP): Fix copy-and-paste error. Problem reported by Hin-Tak Leung.
Werner Lemberg 631e2181 2016-07-14T06:25:05 * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Fix tracing.
Behdad Esfahbod 0f9ddf20 2016-07-14T06:08:39 [truetype] Fix gxvar delta interpolation. The coordinates of the base font should be used for interpolation purposes, NOT the current points (i.e., the result of accumulation of previous deltas). * src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize `points_org' before looping over all tuples.
Werner Lemberg 605946af 2016-07-11T16:14:36 Conditionally compile environment support. * include/freetype/internal/ftobjs.h, src/autofit/afmodule.c, src/base/ftobjs.c, src/cff/cffdrivr.c, src/truetype/ttdriver.c: Decorate with `FT_CONFIG_OPTION_ENVIRONMENT_PROPERTIES' where necessary.
Werner Lemberg 8f8ae8c5 2016-07-11T15:11:38 Handle properties in `FREETYPE_PROPERTIES' environment variable.

Werner Lemberg 474682ff 2016-07-06T08:54:35 * src/truetype/ttinterp.c (TInstruction_Function): Removed, unused.
Werner Lemberg 8ba407a7 2016-06-25T18:09:22 [truetype] Really fix deallocation in case of error (#47726). * src/truetype/ttgload.c (load_truetype_glyph): Thinko; initialize `outline.points' also.
Nikolaus Waxweiler b4598828 2016-05-31T08:39:52 [truetype] Let SHPIX move points in the twilight zone in v40. * src/truetype/ttinterp.c (Ins_SHPIX): Allow SHPIX to move points in the twilight zone. Otherwise, treat SHPIX the same as DELTAP. Unbreaks various fonts such as older versions of Rokkitt and DTL Argo T Light that would glitch severly after calling ALIGNRP after a blocked SHPIX.

suzuki toshiya a7d8bdbc 2016-05-16T21:54:32 [truetype] Improve the recursive reference detector. The previous fix for #46372 misunderstood a composite glyph referring same component twice as a recursive reference.

Werner Lemberg f9be567f 2015-07-09T15:10:31 Better support of user-supplied C++ namespaces. See http://lists.nongnu.org/archive/html/freetype-devel/2015-07/msg00008.html for a rationale. * src/autofit/afpic.h, src/base/basepic.h, src/cff/cffpic.h, src/pshinter/pshpic.h, src/psnames/pspic.h, src/raster/rastpic.h, src/sfnt/sfntpic.h, src/smooth/ftspic.h, src/truetype/ttpic.h (FT_BEGIN_HEADER, FT_END_HEADER): Move macro calls to not enclose header files that contain FT_{BEGIN,END}_HEADER macros by themselves. * src/autofit/aftypes.h [FT_DEBUG_AUTOFIT]: Include FT_CONFIG_STANDARD_LIBRARY_H earlier. * src/truetype/ttpic.h: Include FT_INTERNL_PIC_H.
Werner Lemberg 6f918969 2015-07-04T11:35:28 Minor documentation issue.
Werner Lemberg eb1bba9b 2015-06-30T09:46:39 Fix some clang compiler warnings. * src/base/ftoutln.c (FT_Outline_EmboldenXY), src/cff/cf2intrp.c (cf2_interpT2CharString), src/truetype/ttgload.c (load_truetype_glyph), src/truetype/ttgxvar.c (tt_handle_deltas), src/truetype/ttinterp.c (Ins_INSTCTRL): Fix signedness issues.
Alexei Podtelezhnikov 5aaabb44 2015-06-29T22:46:54 [truetype] Speed up bytecode interpreter. * src/truetype/ttinterp.c (Normalize): Use `FT_Vector_NormLen'.
Werner Lemberg 31d97df9 2015-06-21T19:12:12 Make Jam support work again. This is just very basic stuff and just a little bit tested on GNU/Linux only. I won't delve into this since I'm not a Jam user. * Jamfile: Call `HDRMACRO' for `ftserv.h' also. (DEFINES): Replace with... (CCFLAGS): ... this. * src/Jamfile: Don't call `HDRMACRO' for `internal.h'; this is already handled in the top-level Jamfile. * src/autofit/Jamfile (DEFINES): Replace with... (CCFLAGS): ... this. (_sources): Add missing files. * src/cache/Jamfile: Don't call `HDRMACRO' for `ftcache.h'; it no longer contains macro header definitions. * src/base/Jamfile, src/cff/Jamfile, src/sfnt/Jamfile, src/truetype/Jamfile (_sources): Add missing files.
Werner Lemberg e1862306 2015-06-07T16:11:18 * Version 2.6 released. ======================= Tag sources with `VER-2-6'. * docs/VERSION.DLL: Update documentation and bump version number to 2.6. * README, Jamfile (RefDoc), builds/windows/vc2005/freetype.vcproj, builds/windows/vc2005/index.html, builds/windows/vc2008/freetype.vcproj, builds/windows/vc2008/index.html, builds/windows/vc2010/freetype.vcxproj, builds/windows/vc2010/index.html, builds/windows/visualc/freetype.dsp, builds/windows/visualc/freetype.vcproj, builds/windows/visualc/index.html, builds/windows/visualce/freetype.dsp, builds/windows/visualce/freetype.vcproj, builds/windows/visualce/index.html, builds/wince/vc2005-ce/freetype.vcproj, builds/wince/vc2005-ce/index.html, builds/wince/vc2008-ce/freetype.vcproj, builds/wince/vc2008-ce/index.html: s/2.5.5/2.6/, s/255/26/. * include/freetype/freetype.h (FREETYPE_MINOR): Set to 6. (FREETYPE_PATCH): Set to 0. * builds/unix/configure.raw (version_info): Set to 18:0:12. * CMakeLists.txt (VERSION_MINOR): Set to 0.

Werner Lemberg 75534a04 2015-06-03T00:54:09 [truetype] Fix memory leak. Problem reported by Grissiom <chaos.proton@gmail.com>; in http://lists.nongnu.org/archive/html/freetype/2015-05/msg00013.html there is an example code to trigger the bug. * src/truetype/ttobjs.c (tt_size_init_bytecode): Free old `size' data before allocating again. Bug most probably introduced four years ago in version 2.4.3.
Werner Lemberg 54d04286 2015-06-01T12:12:06 [truetype] While tracing opcodes, show code position and stack. * src/truetype/ttinterp.c: Change all existing TRACE7 calls to TRACE6. (opcode_name): Add string lengths. (TT_RunIns): Implement display of code position and stack.
Werner Lemberg e9df4e47 2015-05-31T12:21:34 [truetype] In GX, make private point numbers work correctly. This is completely missing in Apple's documentation: If a `gvar' tuple uses private point numbers (this is, deltas are specified for some points only), the uncovered points must be interpolated for this tuple similar to the IUP bytecode instruction. Examples that need this functionality are glyphs `Oslash' and `Q' in Skia.ttf. * src/truetype/ttgxvar.c (tt_delta_shift, tt_delta_interpolate, tt_handle_deltas): New functions. (TT_Vary_Get_Glyph_Deltas): Renamed to... (TT_Vary_Apply_Glyph_Deltas): ... this; it directly processes the points and does no longer return an array of deltas. Add tracing information. Call `tt_handle_deltas' to interpolate missing deltas. Also fix a minor memory leak in case of error. * src/truetype/ttgxvar.h: Updated. * src/truetype/ttgload.c (TT_Process_Simple_Glyph, load_truetype_glyph): Updated.
Werner Lemberg 9845c1d4 2015-05-31T11:57:31 [truetype] In GX, make intermediate tuplets work at extrema. * src/truetype/ttgxvar.c (ft_var_apply_tuple): Fix range condition.
Werner Lemberg cdee7d14 2015-05-31T11:54:42 [truetype] Add tracing information to GX code. * src/truetype/ttgxvar.c (ft_var_load_avar, ft_var_load_gvar, ft_var_apply_tuple, TT_Get_MM_Var, TT_Set_MM_Blend, TT_Set_Var_Design, tt_face_vary_cvt): Do it.
Werner Lemberg a678560d 2015-05-28T17:31:15 Minor.
Werner Lemberg a5e1f6f3 2015-05-24T23:29:23 [truetype] Fix commit from 2015-05-22. * src/truetype/ttgload.c, src/truetype/ttinterp.c: Guard new code with `TT_CONFIG_OPTION_SUBPIXEL_HINTING'. Problem reported by Nikolaus Waxweiler <madigens@gmail.com>.
Werner Lemberg 7f099482 2015-05-24T09:50:24 [truetype] Fix return values of GETINFO bytecode instruction. * src/truetype/ttinterp.h (TT_ExecContextRec): New fields `vertical_lcd' and `gray_cleartype'. * src/truetype/ttgload.c (tt_loader_init): Initialize new fields. Change `symmetrical smoothing' to TRUE, since FreeType produces exactly this. * src/truetype/ttinterp.c (Ins_GETINFO): Fix selector/return bit values for symmetrical smoothing, namely 11/18. Handle bits for vertical LCD subpixels (8/15) and Gray ClearType (12/19).
Werner Lemberg bb435da2 2015-05-23T07:21:25 [truetype] Minor. * src/truetype/ttinterp.h (TT_ExecContext): s/subpixel/subpixel_hinting. * src/truetype/ttgload.c, src/truetype/ttgload.h: Updated.
Werner Lemberg c61cad86 2015-05-22T22:02:15 [truetype] Support selector index 3 of the INSTCTRL instruction. This flag activates `native ClearType hinting', disabling backwards compatibility mode as described in Greg Hitchcocks whitepaper. In other words, it enables unrestricted functionality of all TrueType instructions in ClearType. * src/truetype/ttgload.c (tt_get_metrics): Call `sph_set_tweaks' unconditionally. (tt_loader_init): Unset `ignore_x_mode' flag if bit 2 of `GS.instruct_control' is active. * src/truetype/ttinterp.c (Ins_INSTCTRL): Handle selector index 3. (Ins_GETINFO): Updated. * docs/CHANGES: Document it.
Werner Lemberg 790b8dfb 2015-05-20T12:33:40 [truetype] Minor.
Werner Lemberg 0a6b6ff7 2015-05-17T22:54:48 [truetype] Fix loading of composite glyphs. * src/truetype/ttgload.c (TT_Load_Composite_Glyph): If the ARGS_ARE_XY_VALUES flag is not set, handle argument values as unsigned. I trust `ttx' (which has exactly such code) that it does the right thing here... The reason that noone has ever noticed this bug is probably the fact that point-aligned subglyphs are rare, as are subglyphs with a number of points in the range [128;255], which is quite large (or even in the range [32768;65535], which is extremely unlikely).
Alexei Podtelezhnikov 40623a1f 2015-04-27T22:27:00 [truetype] Speed up IUP. * src/truetype/ttinterp.c (_iup_worker_interpolate): Separate trivial snapping to the same position from true interpolation.

Werner Lemberg 10e2bb8b 2015-03-29T13:32:47 [type1, truetype] Make the MM API more flexible w.r.t. `num_coords'. This commit allows `num_coords' to be larger or smaller than the number of available axes while selecting a design instance, either ignoring excess data or using defaults if data is missing. * src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design): Implement it. * src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_Design, T1_Set_Var_Design): Ditto.
Werner Lemberg 6cc425db 2015-03-21T06:51:07 [truetype] Improve `gvar' handling. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Correctly handle single-element runs. Cf. glyph `Q' in Skia.ttf with weights larger than the default.
Werner Lemberg a451638e 2015-03-11T08:09:13 Rename `svxf86nm.h' to `svfntfmt.h'; update related symbols. * include/internal/ftserv.h (FT_SERVICE_XFREE86_NAME_H): Renamed to... (FT_SERVICE_FONT_FORMAT_H): This. * include/internal/services/svfntfmt.h (FT_XF86_FORMAT_*): Renamed to ... (FT_FONT_FORMAT_*): This. src/base/ftfntfmt.c, src/bdf/bdfdrivr.c, src/cff/cffdrivr.c, src/cid/cidriver.c, src/pcf/pcfdrivr.c, src/pfr/pfrdrivr.c, src/truetype/ttdriver.c, src/type1/t1driver.c, src/type42/t42drivr.c, src/winfonts/winfnt.c: Updated.
Werner Lemberg 0aa36160 2015-03-08T22:50:37 Formatting, whitespace, addition of some comments.
Werner Lemberg 328b7923 2015-03-04T08:40:23 [truetype] Some fixes and code refactoring in `ttgxvar.c'. * src/truetype/ttgxvar.c (ft_var_readpackedpoints): Fix return value of `point_cnt' if two bytes are read. Use a more vertical coding style. (ft_var_readpackeddeltas): Use FT_UInt for `delta_cnt' parameter. Use a more vertical coding style.
